Zipker Online Services — wrong product delivered and worst customer service experience

I have placed an order for a saree on zipker app on 16/7/2018. Recieved a wrong product on 17/7/2018. Immediately i have opted for a return and even sent a mail to zipker customer service regarding the same since none of the number given on their app for customer service is available as i had called more than 50 times but no response. After that i had sent so many mails to them even on escalation but they did not respond to any of them and after so many days my issue is still not resolved
